Data Sheet True RMS Bench Multimeters 2831E and 5491B True RMS Bench Multimeters with Features & benefits Dual Display The B&K Precision models 2831E and 5491B The 2831E and 5491B take typical multimeter Up to 50,000 count display resolution are versatile and dependable bench multimeters measurements such as volts, ohms, and amps Basic VDC accuracy of up to 0.02% suitable for applications in education, service and with great accuracy, stability, and basic VDC Dual display to indicate two measurements repair, and manufacturing requiring basic and accuracy of 0.02% on the 5491B and 0.03% on simultaneously reliable measurements. Additionally, these the 2831E. The meters are also capable of AC + DC True RMS instruments enhance your productivity with measuring frequency, period, continuity, and Up to 25 readings per second measurement built-in math functions and USB connectivity, performing diode tests. Readings can be taken at features not found in other bench meters in this a maximum rate of 25 readings/sec with rate price category. Math operations Rel, Max/Min, measurement rates selectable between slow, AC volt and amp measurement over wide dBm, dB, %, and Hold provide educators with a medium, and fast. frequency range (ACV 100 kHz/ACI 20 kHz) convenient tool to teach basic math concepts. Limit mode for Pass/Fail testing Thes multimeters were designed for Built-in math functions: Rel, Max/Min, dBm, cost-conscious users requiring a basic and dB, %, Hold, Compare dependable meter with a broad range of features Resolution offered at a value price.

The display values could be two different measurements or one measurement expressed in different units. For example, you can simultaneously read an AC voltage and a frequency value or a DC voltage value expressed in volts and in dB. Limit Operation Durable rubber bumpers for Front panel fuse added protection and ability compartment for The limit operation lets you set and control the to stack multiple instruments easy fuse values that determine a HI / IN / LO status of replacement subsequent measurements. The meter can be configured to emit an audible alarm when readings are outside of the configured limit. Rear panel Earth ground USB communication interface connection Increase Productivity with PC Connectivity The 2831E and 5491B are programmable via USB and RS232 (5491B only) interface using RS232 Interface (5491B) industry standard SCPI commands. Users can control and configure the instrument from a remote PC and retrieve measurement results for further analysis. The meters can also be remotely controlled using application software (download- able from the B&K website), which supports front panel emulation and data logging of measurement results.
